Schlagintweitella inopinata, a new genus and species of Dasycladales (green algae) from the Upper Jurassic limestones of Romania
Main Article Content
Abstract
Within the Upper Jurassic deposits of the Cioclovina-Băniţa area (Southern Carpathians), an outcrop was identified that most likely corresponds to a cavern fill. In several clasts of this fill, including black-pebbles, we found a dasycladalean alga whose morphological features differentiate it from all other Jurassic-Cretaceous dasycladalean algae with two orders of laterals. This alga is described in the present work as a new species of a new genus: Schlagintweitella inopinata nov. gen., nov. sp.
